6. Start-up
Do not start the pump until the system has been
filled with liquid and vented. Furthermore, the re-
quired minimum inlet pressure must be available at
the pump inlet, see page 129. The system cannot be
vented through the pump.
As the pump is self-venting, it need not be vented
before start-up.
If the inspection screw is to be slackened,
see fig. 8, care should be taken to ensure
that the escaping, scalding hot liquid does
not cause personal injury or damage to
components.

7. Speed selection
The speed switch in the terminal box can be turned
to three positions. The speed in the three positions
appears from the table below:

Change to lower speed settings offers considerable
reduction in energy consumption and less noise in
the system.

has been switched off.
Change the pump performance as follows:

Supply voltage tolerances
The motors meet the requirements to temperature
rise at ±6%.
Furthermore, the motors have been tested at ±10%
of the voltage range. During these tests, the motors
operate without problems and without being ther-
mally cut out.
